abstract: Supplementary functions for item response models aiming to complement existing
  R packages. The functionality includes among others multidimensional compensatory
  and noncompensatory IRT models (Reckase, 2009, <https://doi.org/10.1007/978-0-387-89976-3>),
  MCMC for hierarchical IRT models and testlet models (Fox, 2010, <https://doi.org/10.1007/978-1-4419-0742-4>),

  rater models (DeCarlo, Kim & Johnson, 2011, <https://doi.org/10.1111/j.1745-3984.2011.00143.x>),
